HI, is there any way to add/display an image in the CSV file??

What exactly do you mean? Doesn't make much sense. You can put an image of a URL in a CSV. You can base64 encode an image & embed it.

actually, Like we we show some company logo on PDF similarly i want to show some logo in CSV file .

If you want to include images you're probably wanting to create an XLS file constructed using an XML template. CSV isn't designed to be containing an image as you're wanting, unless, as mentioned by @CD you're talking about images as data and then you'd encode them.
